Topic: Cannot upload to Arduino Mega 2560 (need solution quick!!!!) (Read 1 time) previous topic - next topic


Hello, after a while suddenly i cannot upload any program in the Arduino. If i try another PC it works but after a while te same problem.
I always get next errors:
Code: [Select]
Binary sketch size: 1588 bytes (of a 258048 byte maximum)
avrdude: stk500v2_command(): unknown status 0xc8
avrdude: initialization failed, rc=-1
        Double check connections and try again, or use -F to override
        this check.

avrdude: stk500v2_command(): unknown status 0x01
avrdude: stk500v2_disable(): failed to leave programming mode

i already tried to reinstall the drivers but nothing fixes this. I had this problem om 3 different PC's!

OS: Windows 7


My advice: get a AVR programmer and avoid the USB connection for uploading sketches.

Yes, I insist: the USB controller in UNO and Mega2560 does not work well
